Tribology is the science and engineering of interacting surfaces in relative motion.It includes the study and application of the principles of friction, lubrication, and wear.
Examples of coatings which achieve this were also discussed, including nanocomposite and nanolayered coatings. Mention was also given to so-called ‘duplex’ coating systems, which combine surface treatments with coatings to gain maximum tribological benefits. 2021-3-3 · material. GGB TriboShield® coatings are speciﬁcally formulated to be self lubricating and provide the full range of thermal, mechanical and tribological possibilities that today's polymers can offer.

Tribological and Functional Coatings publications One of the keys to reducing friction and protecting against wear is to coat components with diamond-like carbon (DLC) or hydrocarbon layers. Further functions of components like reflection, sensors and barrier effect are adjusted via PVD coatings. to coatings which have such a thickness that the substrate also plays a role in the tribological response of the surface, i.e., in supporting the coating when under load (otherwise, the coating would be so thick that it would behave as a bulk A coating is a layer of a substance that is deposited over the surface of an object or a part, referred to as the substrate. Whatever the environmental temperature, coatings protect the surface of components and improve surface properties such as wear resistance, wear corrosion, and scratch resistance. Tribological coatings are applied to reduce friction and increase wear resistance on items that will be in moving contact with other surfaces. Tribological coatings are used in applications that are exposed to severe contact forces under which normal thin-film coatings would fracture and lose adherence, thereby forfeiting their protective function. GGB has been putting the world in motion for over 120 years with industry-leading tribological bearings, coatings and assemblies.

Modern and future internal combustion engines generate new issues to solve.
Anodic coatings are produced onto the surface of various components, made of aluminum alloys, in order to enhance their surface properties. The well-known classification of the anodic coatings is given in the MIL-A-8625F military standard, where hard anodic coatings belong to type III (Ref 1).
Nyckelord: Materials Science, Tribology, Ruthenium is extremely temperature resistant, and, thanks to its excellent tribological properties, very long-lived and hard-wearing. Ruthenium plating is smooth, Sandvik offers pre-coated strip steel for the production of bipolar plates and interconnects for different types of fuel cells, such as PEM FC and SOFC. Combined Thin-film and tribological coatings Thin films can modify the superficial properties without affecting the basic bulk material characteristics.
